A neutral atom of an element has a nucleus with nuclear charge 12 times and mass 24 times that of hydrogen. Calculate the number of electrons, protons and neutrons in its stable positively charged ion.

Explanation

To solve the problem step by step, we need to calculate the number of protons, neutrons, and electrons in a neutral atom of an element with a nucleus that has a nuclear charge 12 times and mass 24 times that of hydrogen. We will also determine the characteristics of its stable positively charged ion.

### Step 1: Determine the number of protons
The nuclear charge of an atom is equal to the number of protons in its nucleus. Given that the nuclear charge is 12 times that of hydrogen, and since hydrogen has 1 proton:

\[ \text{Number of protons} = 12 \times 1 = 12 \]
